Hi there, i am looking for some assistance for my FreeSurfer Group Analysis

I have constructed my groups

Class Female HMDHIE

Class Male HMDHIE

Class Female LMDHIE

Class Male LMDHIE

Class Female HMD

Class Male HMD

Class Female HIE

Class Male HIE


And my regressors (to account for age and years of education)

REGRESSORS: 8x3 = 16

Regressor 1= ones for Female HMDHIE

Regressor 2= ones for Male HMDHIE

Regressor 3= ones for Female LMDHIE

Regressor 4= ones for Male LMDHIE

Regressor 5= ones for Female HMD

Regressor 6= ones for Male HMD

Regressor 7= ones for Female HIE

Regressor 8= ones for Male HIE

Regressor 9= age for Female HMDHIE

Regressor 10= age for Male HMDHIE

Regressor 11= age for Female LMDHIE

Regressor 12= age for Male LMDHIE

Regressor 13= age for Female HMD

Regressor 14= age for Male HMD

Regressor 15= age for Female HIE

Regressor 16= age for Male HIE

Regressor 17= Years of education for Female HMDHIE

Regressor 18= Years of education for Male HMDHIE

Regressor 19= Years of education for Female LMDHIE

Regressor 20= Years of education for Male LMDHIE

Regressor 21= Years of education for Female HMD

Regressor 22= Years of education for Male HMD

Regressor 23= Years of education for Female HIE

Regressor 24= Years of education for Male HIE


However, I am now unsure how to create the contrasts and which values to
assign them?


Thanks

Tayla
